The funeral for a man who was chased and shot dead in an apparent road rage attack in Pennsylvania was held Saturday as authorities continue to search for his killer.

Timothy "Asti" Davison, 28, was traveling back home to Poland, Maine, when he called 911 and said a vehicle was pursuing him and that the driver was firing a weapon at him, according to multiple reports.

The person driving a dark-colored Ford Ranger-style pickup then forced Davison's vehicle into a median and fired several rounds into the young man's car. Davison, who was later found shot, died at a hospital, police said.

Since the killing, authorities have said the incident could have been connected to several other shootings.

Most recently, Fox News reported that Davison's murder could have something to do with the murder of Jason Ellis, a Kentucky cop shot and killed along a state highway on May 25 after leaving his car.

Ellis, 33, was driving home at 2:53 a.m. when he stopped along a parkway and began removing debris from the roadway. He was shot multiple times with a 12-gauge shotgun. Police have not been able to solve the case.

Kentucky investigators probing the murder of the police officer plan to contact Pennsylvania authorities to see whether there is a connection, according to Fox News.

"We have to assume the individual is a violent person and might do this again," Pennsylvania State Trooper Robert Hicks told WMTW.
